Usage

Uses

Used in Agricultural Industry:
SIDURON is used as a selective pre-emergence herbicide for controlling annual weed grasses, such as crabgrass, foxtail, and barnyard grass. It is applied to newly seeded or established turf and lawn grasses, as well as a pre-emergence treatment to bare soil following spring seeding. It is registered for use in the U.S. but not listed for use in EU countries.

Trade name

GREENFIELD?; GRO-TONE?[C]; H-1318?; TREY?; TUPERSAN?

Potential Exposure

A phenyl urea preemergence herbicide used to control annual grasses (e. g., crabgrass, foxtail, and barnyard grass) and on newly seeded or established turf and lawn grasses and as bare soil treatment following spring seeding.

Environmental Fate

Soil. A fungus and two Pseudomonas spp. isolated from soil degraded siduron to form the major metabolites: 1-(4-hydroxy-2-methylcyclohexyl)-3-(p-hydroxyphenyl)urea, 1-(4- hydroxy-2-methylcyclohexyl)-3-phenylurea and 1-(4-hydroxyphenyl)-3-(2-methycyclohexyl)urea (Belasco and Langsdorf, 1969). Plant. After 8 days following absorption in barley plants, no metabolites were detected (Splittstoesser and Hopen, 1968).

A novel synthesis of isocyanates and ureas via β-elimination of haloform

A novel synthesis of isocyanates via base-induced β-elimination of haloform from N-monosubstituted trihaloacetamides is described. The rate of reaction exhibits a strong dependence on the nature of the trihalomethyl group. Thus, while the reaction of tribromoacetamides proceeds at room temperature and the reaction of trichloroacetamides requires heating in polar solvents, no reaction could be observed for any of the corresponding trifluoro derivatives. This novel β-elimination of haloform from stable and readily available trihaloacetamides was applied to a 'one-pot' synthesis of ureas which avoids the use of phosgene and isolation of isocyanates.

Herbicidal composition for upland farming and weeding method

A herbicidal composition for upland farming which can control weeds that have been difficult to control, for example, cleavers, chickweed, birdseye speedwell and violet, said composition containing as active ingredients a 3-substituted phenylpyrazole derivative represented by the general formula (I): STR1 (wherein R is a hydrogen atom, a C1-6 alkyl group, a C3-6 cycloalkyl group, a C1-6 haloalkyl group, a C2-6 alkenyl group or a C2-6 alkynyl group, R1 is a C1-6 alkyl group, X1 and X2, which may be the same or different, are halogen atoms, and Y is an oxygen atom or a sulfur atom) and at least one compound selected from the group consisting of sulfonylurea derivatives, phenylurea derivatives and phenoxy fatty acid derivatives; and a weeding method using said composition.
